The main objective of this secondary analysis was to describe the nutritional status of the Better Outcomes in Labour Difficulty (BOLD) project study population and determine possible associations between maternal nutritional status (as reflected by maternal BMI at the time of birth) and severe neonatal outcomes (SNO). We also analysed previous and index maternal pathologies to determine associations with neonatal outcomes. We used the classification designed by Atalah for maternal BMI and compared with the Hyperglycaemia and Adverse Pregnancy Outcome study one. To describe the nutritional status of this population, figures of distribution and test of normality related to weight and BMI were presented for the women and their babies. To explore the association between maternal BMI data and SNO, the χ2 test was performed. To identify a maternal characteristic or a group of characteristics that could predict SNO, we used Fisher’s exact test using previous maternal pathology collected in the BOLD project as well as that in the index pregnancy. In this study, BMI at the time of birth was not associated with neonatal near miss or death. We found that previous maternal obesity, diabetes and chronic hypertension were associated with SNO. Maternal pathology in the index pregnancy such as other obstetric haemorrhage, pre-eclampsia, anaemia and gestational diabetes was associated with SNO.
This systematic review examines the effectiveness and cost-effectiveness of behavioural health integration into primary healthcare in the management of depression and unhealthy alcohol use in low- and middle-income countries. Following PRISMA guidelines, this review included research that studied patients aged ≥18 years with unhealthy alcohol use and/or depression of any clinical severity. An exploration of the models of integration was used to characterise a typology of behavioural health integration specific for low- and middle-income countries.
Fifty-eight articles met inclusion criteria. Studies evidenced increased effectiveness of integrated care over treatment as usual for both conditions. The economic evaluations found increased direct health costs but cost-effective estimates. The included studies used six distinct behavioural health integration models.
Behavioural health integration may yield improved health outcomes, although it may require additional resources. The proposed typology can assist decision-makers to advance the implementation of integrated models.
Although anxiety disorders prevalence and incidence decline in later life, anxiety is a major health problem for the elderly. Epidemiology, neurobiology, and treatment of anxiety disorders are poorly studied in the geriatric population. Nevertheless, anxiety has a high impact on functional status and health-related quality of life.
To underline the significant impact of anxiety in the elderly. to discuss the sub-diagnosis and sub-treatment of late-life anxiety and subclinical symptoms.
Literature Review. MEDLINE and PubMed databases searches for peer-reviewed studies, published between 1998 and 2008, using combinations of the Medline Subject Heading terms anxiety, anxiety disorders and old age.
There are few studies in the literature addressing this topic. Late-life anxiety has a high prevalence and is associated with increased morbidity, mortality, functional impairment, poorer quality of life and significant societal costs. Clinical studies show that most cases of anxiety disorders in late life are undetected and under-treated. Intervention research in late-life anxiety disorders is lacking.
It is extremely important and urgent a more efficacious assessment and management of anxiety disorders in the elderly. It is also fundamental an increased attention to subtreshold anxiety, which will allow an earlier intervention and prevention of new cases of anxiety disorders. Well designed interventions will be capable of reducing the burden, morbidity and incidence of late-life anxiety.
This study was designed to verify whether fluoxetine (FL), a serotonin (5-HT) re-uptake inhibitor, would interfere with nortriptyline (NT), a biphasic U-shaped curvilinear dose-response relationship recently described in our laboratory. We associated 10 mg/kg NT or vehicle to 0, 5, 10, 20 and 40 mg/kg FL, in one group, and 10 mg FL or vehicle to 0, 5, 10, 20 and 40 mg/kg NT, in another group, 30 min before the tail suspension test (TST) in mice. Although we were not able to confirm a synergistic effect between FL and NT, FL-NT association seems to require higher doses of NT to block its own anti-immobility effect at high doses, thus widening NT effective antidepressant-like dose range in mice submitted to TST.
Besides preventive, maintenance and rehabilitative measures, it is very important that Psychiatry Services develop acute care interventions that include hospitalization treatments. Compulsory treatment is mandatory when patients have a severe mental illness that deprives them from their judgement abilities in such a way that they deny their illness, refuse necessary treatment, and may endanger themselves and/or others.
To compare socio-demographic and clinical features of patients treated in compulsory and voluntary regimen. To make a reflection on the most suitable model for the acute inpatient services.
Retrospective study of socio-demographic and clinical characteristics of patients admitted in an acute inpatients’ unit of a Psychiatric Hospital - Hospital de Magalhães Lemos - in 2006 and 2007. We compared data of compulsory (CA) and voluntary admissions (VA), and discuss their respective main problems.
Among the total 577 inpatients admitted, 13% were compulsory and 87% were voluntary. Schizophrenia was the most prevalent diagnosis in both groups (51% CA vs 26% VA). By discharge, prescription of depot antipsychotics was higher in CA, and treatment with antidepressants was higher in VA. In CA, 8 (11%) patients had discharge against medical advice (escape) vs 12 (2%) in VA.
Results might suggest that the current facilities and/or procedures are not sufficient to offer the levels of protection needed to provide the best environment for patients’ recovery.
In the context of the recent efforts towards the reorganization of mental health services, specific measures should be considered, including acute inpatients units exclusively designed for CA.
Déterminer si l’emploi addictif des nouvelles technologies (Internet – Jeux vidéo – Téléphone portable – Télévision) par les adolescents pourrait partager la même cause que celle qu’on observe dans les troubles alimentaires et dans les troubles d’externalisation, avec des altérations dans l’impulsivité, et partager également la même dysfonction neuropsychologique.
Introduction et objet
Les nouvelles technologies fournissent une meilleure qualité de vie, le problème est leur potentiel de dépendance surtout chez les adolescents souffrant de troubles du contrôle des impulsions, en particulier des troubles alimentaires et des troubles d’externalisation.
Il s’agit d’une étude descriptive et comparative. Le diagnostic s’établit selon notre protocole (DSM-IV/CIE-10), et selon l’application de trois instruments différents : BIS.11 (Barratt-échelle-de-l’impulsivité), DENA (questionnaire-de-dépistage-des-nouvelles addictions), IAT (Test-d’Addiction-à-l’Internet). La population a été divisée en deux groupes : les troubles de l’alimentation (n = 10) et les troubles d’externalisation (n = 10), dans la fourchette d’âge 12 à 17 ans, dans nos centres-d’ITA.
Les résultats ont démontré que le modèle de l’impulsivité est plus élevé chez les adolescents atteints de troubles de l’externalisation que chez ceux souffrant de troubles alimentaires. Les deux groupes avaient une tendance similaire dans l’utilisation des nouvelles technologies.
L’usage et l’abus potentiel des nouvelles technologies est similaire chez les adolescents hospitalisés pour troubles de l’alimentation et ceux hospitalisés pour pathologies liées à des troubles d’externalisation, ouvrant une zone problématique : celle de la canalisation de l’impulsivité dans l’emploi des nouvelles technologies. Il est nécessaire de mener à terme des recherches avec plus de population d’appui, ce qui pourrait fournir des lignes directrices en faveur d’une approche clinique.
Bipolar disorder is a chronic, recurrent and debilitating mood disorder with a major impact on several aspects of everyday life. Although pharmacotherapy plays a central role in bipolar disorder treatment, psychosocial interventions are essential to a more complete and successful treatment.
To present a psychoeducation program for bipolar patients runned in a Portuguese psychiatric hospital - Hospital de Magalhães Lemos, Oporto. To review the impact of psychoeducative measures on bipolar patients.
A psychoeducative program for bipolar patients was developed and adapted, based on the Barcelona Bipolar Disorders Program"s experience. The psychoeducative program was applied to bipolar patients as an adjuvant of maintenance treatment.
Fifteen sessions were runned during 15 weeks. Twelve patients were recruited to integrate the psychoeducative group. The sessions addressed several topics including information about the illness, early detection of prodromal symptoms and symptoms management, stress management and the importance of maintaining routines.
The best treatment available for patients with bipolar disorder includes, along with the pharmacological treatment, psychosocial interventions aimed to target issues as early identification of prodromal symptoms, coping skills, medication adherence and understanding of the disorder. This broader approach of bipolar disorder treatment has proved to be efficient in reducing relapse rates, and improving patients’ feelings of self-efficacy and quality of life.
Subjective Memory Complaints (SMC) are common in clinical practice. the clinical significance of these subjective complaints among older individuals is not well understood.
To study and discuss the association between SMC and MCI, underlining the importance of an adequate clinical assessment of SMC in the elderly.
Review of the literature.
There is no consistent definition of SMC in the literature. Some prospective studies showed an association with objective memory impairments, conceptualizing SMC as a Pre-Mild Cognitive Impairment. SMC are also currently considered to be a core feature of Mild Cognitive Impairment (MCI). Cross-sectional studies and longitudinal studies showed conflicting results concerning the association between SMC and MCI.
The understanding of the predictive value of SMC in cognitive decline is still poorly understood. It is important to define criteria aimed to increase specificity of memory complaints, allowing an earlier identification of populations with higher risk of MCI. Future research on this complex association is important to identify SMC individuals at increased risk of conversion to MCI and dementia.
Eating disorders, represented in the spanish adolescent population a prevalence of 3,5% to 5,5% (Labrador-and-Raich.2007), increasing day by day in our treatment centres. Multiple diseases are based on the pattern of Impulsivity, which must be studied in their overall comorbidity, because the general approach to their differents etiologies, could have a focus on a Unique Therapeutic Plan (UTP).
There is a high comorbidity between the Impulsivity seen in Eating Disorders(ED) such as Bulimia Nervosa, Obesity, Binge(ED), Pica, among others, and externalizing disorders, because of their low tolerance to frustraction and low awareness of delimit, and many times there is also the presence of disorders related to substance use.
Demostrate by reviewing a case, the diagnostic comorbidity between Bulimia Nervosa and one type to Attention Déficit Disorder with Hyperactivity, associated with a pattern of substance abuse, with the same effective psychoterapeutic and psychofarmacological treatment, and demostrading, the posible same Neurobiological root.
Adolescent with 16 years old, with four years ago of hyporexia, vomits and binge, with hyperactivity, inattention and impulsivity. (BMI=17), in the context of greater family dysfunction and school bullying. There was cannabis abuse. He had received treatment with antipsychotics, antidepressives and mood stabilizers. By age 14, he was diagnosticated of Bulimia Nervosa in comorbidity with Attention Deficit Disorder with Hyperactivity in the Eating Disorders Institute(ITA). The new psychopharmacological treatment was with Methylphenidate, but he had tachycardia, also it suspend, and started Atomoxetine, associated with psychotherapeutic management and family therapy. Now the evolution is excellent(CHIP-AE), and there is absence of substance use over 12 months.
The eating disorders, with impulse control deficits, keep high etiopathogenic relationship with externalizing disorders-ADHD-, and could be effective the same psychotherapeutic and psychopharmacological treatment.
A very important determinant of school performance is attention deficit disorder with or without hyperactivity or impulsivity. the criteria established by the DSM-IV-TR are one of the most widely accepted procedures to diagnose the deficit. There are three different subtypes: inattentive, hyperactive-impulsive and combined. Gonzalez-Castro et al., (2010) demonstrated empirically that the subtypes of ADHD often score significantly different in the prefrontal and central areas of the cortex. This is the reason why it is convenient to carry out more studies in the measure of Q-EEG (electrical activity) combined with that of nir-HEG (blood activity). Rodríguez, et al., (2011) apply both instruments (Q-EEG and nir-HEG) to a sample of 70 students and verify that the nir-HEG differentiates significantly the ADHD subjects of the control group and the combined and inattentive subtype for the Fp1 variable, associated to the executive control. These results might be caused by the time taken to do the evaluation (35 seconds). Therefore, the reason of this research is to assess the instrument over a long period of time while performing a continuous performing task (CPT). the results show statistically significant differences between the control group and the other with ADHD and among the subtypes in the variables of executive control and short evaluation with the nir-HEG. As for the long evaluation of blood oxygenation during a performance of an executive task, some differences can be seen among the subtypes with ADHD, although not statistically significant.
Emotional dysregulation is a characteristic present in many child adolescent mental pathologies. It can be found in Eating disorders(ED), and in the bipolar spectrum too. Highlighting similarities between a softer bipolar spectrum in its sub-threshold forms and eating disorders syndromes and sub-syndromes in adolescents.
Evaluate the emotional dysregulation (measured by the HCL-32),and eating habits (measured through the BEDS),in a population with:ED.
This is a transversal, observational study in a group of 40 patients between 12 and 19 years of age, all of whom were diagnosed with ED before they turned 18 and receive inpatient treatment. The group was divided into two subgroups: Group-I:Anorexia Nervosa-AN (n=17), and Group-II: Bulimia Nervosa-BN (n=23). They were evaluated with two scales: Hypomanic Checklist (HCL-32) and Barcelona-Bipolar-Eating-Disorder-Scale(BEDS); with different clinical and sociodemographic characteristics.
Group I-AN showed higher scores in HCL-32, which was not correlated with the BEDS total score. Group-II presented high scores in HCL-32,showing a positive correlation with the BEDS total score (r=0,518;p=0,011), mainly in the subscale symptoms of hypomania associated with a lack of inhibition, self-control and attentional capacity.(r=0,461;p=0,027).
Emotional dysregulation is a factor to be considered in the diagnosis and clinical management of patients with ED, and may imply other comorbid conditions. Furthermore,Bulimia Nervosa,especially in cases with emotional dysregulation could be related to hypomania or a bipolar spectrum.
BEDS Scale may be related to emotional dysregulation in patients diagnosed with Bulimia Nervosa and high score in the scale of hypomania HCL-32, not so for the Anorexia Nervosa.
Although investigation have demonstrated that stimulants are effective medication for the treatment of the symptoms on the ADHD, a commonly described but quite slightly studied side effect of this type of medication, is the effect on the emotional expression of patients.
evaluate the effect of the treatment with Methylphenidate on the affective/emotional expression in children diagnosed with ADHD.
It's a descriptive study of several cases series, from a center and about a unique group, where 'n” will be 15 children diagnosed with ADHD at the University Hospital, who were required beginning treatment with methylphenidate, with a daily dose of at least 0,3mg/Kg. In this study it will be evaluated the emotional expression of the group, according to the scale Expression and Emotion Scale for Children (EESC) making a comparison between the previous moment to the treatment and a subsequent month from its beginning.
The evaluation of the total result of the EESC conducted by the parent didn't show statistically significant differences between scores previously of the treatment and results after a month with it. The dominions (positive emotions, emotional flatness and emotional lability) didn't show differences between both periods of time, nevertheless, the positive emotions showed a tendency of reduction more showy than the rest, without getting to be statistically significant (p=0.0638).
Statistically there haven't been significant changes in the emotional expression of the children caused by the treatment with methylphenidate. Nevertheless, the data show that there is a tendency to an improvement in it.
Association between attention deficit hyperactivity disorder (ADHD) and reading disorder (RD) is frequent. They are two of the most common disorders among school-age children and co-occurrence of both disorders range from 20% to 40% (Bental et al., 2007; Willcutt et al., 2010). Our main goal was to know if both disorders share common executive deficits and which are the main deficient areas.
we assessed the executive functioning in a sample of 79 children and teens with ADHD (n = 43) and ADHD+RD (n = 36), aged 6 to 16, through the administration of the BRIEF-Parent form (Behavior Rating Inventory of Executive Function; Gioia, Isquith, Guy, & Kenworthy, 2000). This scale measures eight components of the executive function, focusing in daily behaviors associated with executive functioning. However, it is not available in Spanish language. for this reason we translated the scale into Spanish and we made an exploratory study with an initial sample of 90 boys and girls, aged 5 to 18, getting some acceptable psychometric properties.
The co-morbid group shared the basic characteristic impairments in executive functions with the pure ADHD. in addition, this group showed a more severe impairment in working memory, monitor and planification.
the results point to a different and more impaired clinical profile in the co-morbid condition. Finally, executive functioning should be considered in the diagnosis of RD and in the design of reading learning programs, which have been focused primarily on the linguistic nature of the task forgetting other possible relevant domains.
Pregnancy may cause somatic alterations and possible transformation in women's behaviour, emotions and cognition.
To analyse monthly somatic and cognitive changes in pregnancy.
To examine the pattern of cognitive (depressed mood, lack of self-esteem, guilt, lack of concentration, sensitivity to criticism, thoughts of death) and somatic (decreased energy, feelings of heavy limbs and feeling worse in the morning) symptoms throughout the 9 months of pregnancy.
N=374 women were interviewed once (6 weeks postnatal) using a modified version of the Structured Clinical Interview for DSM IV. Women were asked whether they had experienced each symptom at any time during pregnancy and if they said yes, the monthly symptom occurrence was assessed. Repeated measures General Linear Model analysis was used.
There were both linear (a) and quadratic (b) significant changes over time for sensitivity to criticism (Fa=20.9(1), Fb=7.02(1), pa,b=0.00), lack of concentration (Fa=37.0(1); Fb=10.3(1); pa,b=0.00), decreased energy (Fa=13.4(1), Fb=62.6(1); pa,b=0.00) and feelings of heavy limbs(Fa=92.9(1), Fb=67.7(1) pa,b=0.00). Guilt (F=0.00(1); p=0.93) showed no change over pregnancy, lack of self-esteem (F=10.15(1); p= 0.00) showed linear significance while depressed mood (F=5.15(1); p= 0.02) showed quadratic significance. After controlling for covariates, no significant interactions between them and all symptoms were found.
Cognitive symptoms changed throughout pregnancy as much as somatic symptoms. Most symptoms showed a different pattern from depressed mood (Figure 1). Sensitivity to criticism, lack of concentration, feelings of heavy limbs and decreased energy were especially high during late pregnancy.
Behavioral disorders at school have negative consequences for students' social development and academic achievement. A better understanding of their causes would help to develop more adapted prevention and intervention strategies. This study analyzes the association between behavioral disorders and executive dysfunctions in Elementary School students. A sample of 974 students from third to sixth grade of Primary School (aged 7 to 12), belonging to 30 schools in Asturias (Northern Spain), as well as their families and teachers, took part in this study. Behavioral disorders were assessed through teachers' completion of ACE rating-scale (Arias, Ayuso, Gil & Gonzalez, 2009). The frequency of occurrence of behaviors associated with deficits in nine executive functions (impulsivity, hyperactivity, emotional control, functional memory, planning, organization, cognitive flexibility, concentration and focus) was assessed by means of the EFE scale (developed by the authors) in its three forms (student self-report, and teachers and family rating-scales). Spearman correlation coefficients between scores obtained in ACE and the nine executive functioning components of EFE scale in its three forms were calculated. Statistically significant correlations between both measures were obtained. The strongest correlations were found between disruptive behavior and Impulsivity, Hyperactivity and Emotional Control. Results were consistent for the three forms of the EFE scale, being correlations higher when teachers were the informant. This study highlights the relevance of considering executive functioning components for the prevention and treatment of behavioral disorders.
The Eating Disorders (TA) are characterized by severe eating disorders, and anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED), the most common types. May be associated with medical and psychiatric comorbidities. They tend to be perfectionists, they suffer from low self-esteem and extremely critical with respect to weight and body shape. The impairment and loss are common occupational roles in most cases. Describe multidisciplinary Consulting Group Program in models of the International Classification of Functioning, Disability and Health (ICF) of the working methodology of the Treatment Plan Singular in skilled nursing. Experience Report. Customer in open group average of 10 participants, twice a week with each 1h30' during hospitalization period between 3-6 months and participation of one social worker, one nurse and one occupational therapist. Most are women between 22 and 38 years and diagnosis of AN and BN. The program aims to share the life planning, raising awareness of their actions and behaviors and their functional and health condition, relating to the environmental context. Actions primarily focus on motivation and awareness for behavior changes and resumption of occupations, and later experimentation with insertion or recovery activities and occupations. It is observed that this work contributes to awareness for behavior change, identifying demands resumption of occupational roles and restructuring of the routine. Other services can benefit from this program, avoiding prolongation of hospitalization, possible new admissions or the distance between the same intervals.
Determine if the use of new technology (The Internet-Videogames-Mobile Phones-TV) by adolescents, could share the same pattern, even adiction, as seen in eating disorders-ED, and externalizing disorders.
Introduccion and Purpose
New technology provides a better quality of life. The problem is their addictive potential for adolescents, and about all, in young people with impulse control disorders, such as eating disorders (bulimia Nervosa, obesity, binge disorder, pica, e.g) and externalizing disorders (attention deficit hyperactivity disorder, conduct disorder, oppositional defiant disorder, e.g) in the Institute of Trastorns Alimentaris-ITA, and our program ITA-Conduct.
This is a descriptive-comparative study, with diagnosis, according to our protocol(DSM-IV/CIE-10), and the application of four individual instruments: BIS.11 (Barratt-Impulsiveness-Scale),DENA(Screening Questionnaire of New-Addiction),IAT (Internet-Addiction-Test), and PVP (Problem-Video-Game-Playing). The population was divided into two groups:Eating Disorders(n=12) and Externalizing Disorders(n=14), within the ages of 12 to 17 years old, at our Argentona and Barcelona Centers, in treatment inpatient.
There is not significative differences in the Impulsivity(cognitive, motor and unplanned)among ED and externalizing-disorders. The unplanned impulsivity is associated with higher scoring in trials to Internet Addiction and Video-Game-Play. The mobil-phone use is higher in ED.
The use and potential abuse of new technology is similar in adolescents hospitalized for Eating Disooders and pathologies related to Externalizing Disorders, providing a problematic area: channeling symptoms without a proper approach of its implications.
Currently, there are many drugs to treat Attention Deficit Disorder with Hyperactivity. in addition, what has prover to be complimentary to drug therapy is behavioral training for parents and teachers as well as training on social skills and behavioral modification. Current studies using nir-HEG (blood activity), which, significantly differentiate ADHD children in the control group and the combined and inattentive subtype for the variable Fp1, associated with executive control. the instrument nir-HEG instrument allows the training of cortical activation favoring the increase of the latter. in 2000, Toomim et al performed a treatment study with a group of 26 subjects. Most (14) had been diagnosed with ADHD and each participant was submited to an evaluation of 10 sessions (in three areas of the prefrontal cortex). Participants in the experimental group showed a gain of nearly one standard deviation in TOVA. in this study, a five-subject design case was employed and ten sessions of HEG were administered. However we show another results contrasting nirHEG measures (ratio, attention index) with another attention measure. Data showed positive gain indicating success when increasing the biofeedback signal. for example children trained with HEG, gain a significant improvement in terms of selective and sustained attention. However, the gain of the experimental group at the end of training is important and can amount to 31.5%. the results open a scope of great interest to be more precise in the intervention from the behavioral and pharmacological point of view.
Comorbidity between alcoholism and depression has long been acknowledged, and the possibility that similar brain mechanisms, involving both serotonergic (5-HT) and noradrenergic systems (NE), underlie both pathologies has been suggested. Thus, inhibitors of NE and 5HT uptake have been proposed for the treatment of alcoholism, as they have shown to reduce alcohol intake in various animal models. However, most of the studies mentioned were carried out acutely and there is a lack of knowledge of the possible long-term effects. Clinical studies report an overall low efficacy of antidepressant treatment on alcohol consumption, or even a worsened prognosis. In addition, several cases of alcohol dependence following antidepressant treatment have been reported in the literature.
We aimed at comparing the acute and chronic effects of the treatment with the antidepressant drug reboxetine on alcohol consumption.
We used a rat model of alcohol self-administration, and two different schedules of reboxetine administration (acute and chronic).
Our results confirm the acute suppressant effects of reboxetine on alcohol consumption but indicate that, when this drug is administered chronically in a period of abstinence from alcohol, it can significantly increase the rate of alcohol self-administration.
These results are important for the understanding of the clinical reports describing cases of increased alcohol consumption after antidepressant treatment, and suggest that much more research is needed to fully understand the long term effects of antidepressants, which remain the most widely prescribed class of drugs.

The description of the movements and habitat preference of marine fishes is essential to understand their biology and in the evaluation of commercially exploited species and the conservation of endangered ones. In this regard, little is known about the movements of the totoaba (Totoaba macdonaldi), despite its being listed as critically endangered and having been a relevant fishery resource in the past century in Mexico. Totoaba is a fish species endemic to the Gulf of California characterized by late maturation, prolonged life and annual reproduction. Totoaba has maintained its known historical distribution range, although its movements and habitat occupancy in the water column have remained poorly understood. The present study describes, for the first time and at a daily fine scale, the vertical movements and habitat preferences of the totoaba in the Upper Gulf of California. Pop-up satellite archival tags (PSATs) were used to record depth and temperature at 4-minute intervals. Ten individuals were caught and tagged in May 2016 in the Upper Gulf of California and Colorado River Delta Biosphere Reserve. All PSATs were either prematurely released or lost. Data derived from two recovered tags that saved data for 43 and 75 tracking days, respectively, were analysed. The results showed that tagged fishes moved southward to the vicinity of Angel de la Guarda Island; these are consistent with spatial displacement patterns reported in the literature, with a linear displacement of 223 km from deployment to pop-up sites. Fish spent 47% of the time within a depth range of 25–35 m. Depth increased to 70 m for one fish in early summer (late June). The preferred temperature of fishes ranged between 21–23°C. A generalized linear model revealed that vertical movement was influenced by temperature. The vertical displacement of the totoaba shows a diurnal variation that may be associated with the distribution of its prey. Further work is needed to test this hypothesis with a larger number of organisms.
